高放废液处置场选址勘察特大构造破碎带的钻进工艺

Drilling Technology for Location Investigation of Deposit Site of High-radioactive Waste Fluid in Tectonic Fracture Zone

摘要:

高放废液处置的特殊性决定了它对选址勘察中钻探施工有极其严苛的要求。在钻探工艺方面受到了多方面的限制，对钻探施工影响极大，尤其是遇到特大构造破碎带、地层极为复杂的情况下，对钻探是极大的考验。在甘肃北山BS02号孔施工中，通过采用多种不同技术措施，钻穿了十月井特大构造破碎带和复杂地层，满足了设计要求，保证了工程质量和水文地质试验效果。

Abstract:

The particularity of high-radioactive waste fluid deposit determines the very strict requirements on the drilling construction for the location investigation of deposit site, especially in the exceptional large scaled tectonic crushed zone and complicated geological conditions. During the drilling operation of BS02 in Beishan of Gansu, many different technical measures were used, the large tectonic crushed zone and complicated formation were drilled through for Shiyuejing construction to meet the design requirements and ensure the engineering quality and hydrogeological test effect.
